swift - Extra \N{...} when using kCFStringTransformToUnicodeName or NSStringTransformToUnicodeName -

- 

let string = "\u{00a0}" // no-break space let transformed = string.stringbyapplyingtransform(nsstringtransformtounicodename, reverse: false)

expected result: no-break space

actual result: \n{no_break_space}

why \n{ , }? for, , there way remove them, short of regex/scanning/parsing/etc?

that's way icu & unicode represent named code points in regular expressions. i'm not surprised output @ all.

here link reference syntax @ unicode.org.

that's explained in other page @ icu project.

ps: \n{} shorter equivalent \p{name=…} — explained in unicode.org page above linked anchor). can see similar syntaxes in regular-expressions.info mention \p{…} syntax defining unicode codepoints using properties.
